Tuned for Low Mass: XRAY 305987 Narrow Pinion

Made for racers and club drivers, the XRAY 305987 Narrow Pinion Gear uses aircraft duraluminum to achieve a 25% reduction in weight versus typical pinions. Its narrower 1.5mm profile lowers rotational inertia to help the drivetrain pick up speed faster.

Precision Machining and Protective Hardcoat

Manufactured on a specially modified gear cutter, each pinion meets strict concentricity standards. Teeth and edges are chamfered, parts are given a thorough run-in, and a hardcoat is applied to improve wear resistance and preserve quiet operation with matching spur gears.

Versatile Fit and Straightforward Installation

The XRAY 305987 fits a wide selection of spur gears and works especially well with XRAY gear sets to minimise gear noise. It is suitable for both upgrades and routine replacement, delivering dependable performance out of the box.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Does the XRAY 305987 suit brushless setups?

Yes, it is compatible with brushless drivetrains so long as the pinion fitment matches the motor shaft and spline pattern.

How durable is the hardcoat under heavy use?

The hardcoat improves surface hardness and resistance to wear, but routine inspection and correct mesh settings remain important for long life.

Any tips for reducing gear noise?

Ensure precise mesh, chamfer both gear faces where needed, and pair the pinion with a compatible, well-cut spur gear to reduce whine.
